SECTIONAL BOILER.

SPECIFICATION forming part of Letters Patent No. 365,402, dated June 28, 1887.

Application filed April 23, 1887.

To all whomit may concern.-

Be it known that I. Docron F. MORGAN, a citizen of the United States, and a resident of the'city of Akron, in the county of Summit and State of Ohio, have invented a new and useful Improvement in Sectional Cast-Iron Boilers, of which the following is a specification.

Myinvention has relation to improvements in cast-iron sectional boilers for heating purposes.

The objects of my invention are to increase the heating-surface, to prevent the accumulation of soot and ashes on the parts which project into the updraft-space, and, by means of a removable magazine, to permit all partsof the updraft to be easily cleaned, to remove the dust and gases from the ash-pit, and to provide a damper which, in addition to the ordinary dampers, shall be actuated by the changes of steanrpressure.

My invention consists of. the devices illustrated in the accompanying drawings, as hereinafter described and claimed.

Iuthe accompanying drawings, Figure 1 is an elevation of a complete boiler embodying m 'im rovernents- Fi 2 a vertical central section of the same-at the line a; w of Fig. 4.;

- Fig. 3, a similar View of the water-sections at which register with the ports in the next upper section, and'spacesf opposite the flues in'said section. Above thefire-pot are a number of sections, E, each consisting of a hollow ring having fines F and water-ports c. From the inner race of each ring project pairs of hollow arms 0, the inner ends of each pair united by a tube, a, concentric with the section, and integral with the arms. The arms 6 and tubes 6 are triangular in crosssection, one angle being upward, which prevents an accumulation of soot and ashes being retained thereon, and are narrower vertically than the sections Serial No. 213531117. (No model.)

from which they project, so thata space exists between the arms of contiguous sections,thereby not onlyafl'ording additional heating-surface for the updraft, but enabling them to be readily cleaned from adhering particles of soot and ashes.

. In building up the boiler each section E is so arranged that the arms 6 alternate vertically with those ofcontiguous sections. Above the sections E is a top section, G, substantially the same as those in boilers of this class, and which needs no explanation. The whole is illclosed in a case, A, and has the ordinary direct and downdraft fines, H J, (the former having the gate 11,) connecting with the main up- The magazine consists of a tapering castiron ring, m, which rests on the tubes 6 of the lower section, E, with a channel in its upper face, and a hollow cylinder, M, preferably of sheet metal, which rests in said channel, and is supported laterally by the tubes e of the upper sections and registers with the feed hole in the section G. The cylinder M is removable, and thus permits the inner parts of the section-rings to be cleaned.

The boiler is provided with the common draft-regulating valve, N, and with the lever P, which, by the rod n, operates the damper 0.

Between and connectingv the ash'pit B and flue K is a flue, I, with a valve, i. \Vhen the valve 13 is open, the flue I operates to remove dust and gases from the ash-pit into the -uptake K. The valve has an arm connected with the lever I? by the rod 1), by which arrangement the valve i is operated by the valve N, and opened as the damper 0 is closed, therebydrawing away any air that may leak or otherwise enter the ash-pit, and preventing it from passing through the fire.

I claim.

1. The combination, in a cast-iron section for heating-boilers consisting of a hollow ring having water-openings in each horizontal face and fines passing through it, of aseries of pairs of hollow arms, triangular in cross-section, pro-- jecting from its inner face, the inner ends of each pair being united bya tube, triangular in cross-section, concentric with the section, substantially as shown, and for the purpose specified.

2. In a cast-iron sectional boiler, the com bination of a number of waterseetions, each consisting of a hollow ring having dues and water-openings which register with corresponding fines and water-openings in contiguous sections, and a series of pairs of hollow arms, triangular in cross-section,which project from the inner face of a ring, and segmental tubes, triangular in crosssection, which unite the ends of each pair of arms, substantially as shown, and for the purpose specified.

3. In a cast-iron sectional boiler, the combination, with a series of sections each consisting of an outer ring and a series of inner segments, ofa magazine consisting of a castiron ring supported by the segments of the section above the fire-pot, and ahollow cylinderwhich unites with said ring and registers with the feed-opening in the upper section.

4. In a heating-boiler, the combination, with a fine which connects the ashpit with the uptake-flue and gate therein, of a steam-pressure'valve which opens said gate as the steampressure increases, all constructed and arranged substantially as shown, and for the purpose specified.

In testimony that I elai in the foregoing I have hereunto set my hand.

DOCTOR F. MORGAN.
